It may be a bit academic now, but I have been using Grado SR80 headphones for several years and not only do they sound great, but also feel comfortable (which is essential for those long listening sessions....). Recently after years of heavy usage the earpads were beginning to get tatty, and I thought the purchase of a new set of headphones would be my only option, but found I could replace the earpads for a fraction of the cost. Big thumbs up.
